I continue to be confused about whether/when you're allowed to draw causal arrows from mathematical to physical facts.
@MemberOfSpecies Main intuition of “cause” is counterfactuals, and there isn’t a possible world in which 5x5!=25

@Meaningness "If 5x5 had been 26, this 5x5 room would have been 26 square meters" doesn't make zero sense to me. -
@MemberOfSpecies but in any case, in the standard (Kripke) formulation, all mathematical facts are the same in all possible worlds. - 8 more replies

@Meaningness I think people use counterfactuals of that form a lot, only the mathematical facts are a lot more complicated than 5x5=26. -
@MemberOfSpecies Example of more complicated fact being used often? - 2 more replies
